Given numbers are 225, 805, 981, 156

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(225, 805) = 36225

GCD(225, 805) = ( 225 x 805 ) / 36225

= 225 / 805

= 225

Step2:

LCM(5, 981) = 4905

GCD(5, 981) = ( 5 x 981 ) / 4905

= 5 / 981

= 5

Step3:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 225, 805, 981, 156 is 1
